, 3 Claimsu (01.160-23) This invention relates to a storm window, and itconsists in the constructions, arrangements and combinations hereindescribed and claimed.

It is an important object of the invention to provide a construction ofstorm window which may be readily incorporated in standard sash, eitherupon the inside of the building or outside thereof.

More particularly, it is an object of the invention to provide a stormwindow construction in which a sheet of flexible glass is employed, thestructure embodying roller means whereby the flexible sheet may bereadily drawn into position before a window, or be readily raised to aninoperative stored position.

It is a still further object of the invention to provide a storm windowof the type stated in which means are provided for protecting theflexible transparent sheet against scratches, or abrasions duringmovement of the sheet from operative to inoperative position, or viceversa. Additional objects, advantages and features of invention will beapparent from the following description considered in conjunction withthe accompanying drawings, wherein Figure 1 is a front elevation of thestorm windown, partly in section.

Figure 2 is a longitudinal section thereof.

Figure 3 is an enlarged cross section on the line 3-3 of Figure 1.

Figure l is an enlarged fragmentary vertical section illustrating anoperating means for effecting raising and lowering of the transparentsheet.

Figure 5 is a front view thereof, a lower portion of the framing beingbroken away.

Figure 6 is a modified form of take-up means for the flexible sheet.

Figure '7 is a further modified form of the device.

Figure 8 is a still further form of the take-up means.

There is illustrated a window frame In, indicated by dot and dash linesin Figures 1 and 2, since the construction of frames will vary and formno part of the present invention.

As shown in the present instance, the storm window ii is mounted uponthe interior of the building and consists of a substantially rectangularframe I! of a dimensionto fit within the opening defined by the windowframe l0.

Upon the upper end of the frame ll there is suitably mounted a canopy[3, having a closed top and front, the bottom of which is open for apurpose as will presently appear, As may be seen in Figure 1, the canopyis approximately the same width as the window frame and upon the innerfaces of end walls l4 suitable brackets ii are provided for revolublymounting respective rollers l6 and H. The rollers l8 and I! employ arewinding spring, such as found in conventional shade rollers, and sincethis is well understood, a detailed showing is not believed essential tothe full understanding of the invention. It will be seen that the rollerI1 is mounted below the roller l8 and to one side of the longitudinalaxis thereof, and upon the roller ill, a protective sheet I8 is wound,the free end of which is interleaved or rolled between the flexibleglass sheet l8 wound upon the roller I8. Thus the sheeting l8 willprotect the glass sheet ill when it is rolled upon the roller it.

As may be seen from Figure 3, the vertical uprights of the frame l2 arechannel shaped, the channels 20 being presented toward each other.Adjacent the upper ends of the channels 20, a shaft fl is journalled,having respective sprockets f2 fixed at the ends thereof, and occupyinga position within the channels. At the lower end of each channel a studshaft 23 is mounted, having a sprocket 24 in alignment with respectivesprockets 22. A ladder chain 25 is trained about each pair of sprockets22 and 24.

The flexible glass sheet is of a width to present respectivelongitudinal edges within the channels 29, so as to be freely movablevertically thereof, and preferably lies quite close to a reach of thechains 25 so that it may be secured to the chains by means of a lug 2B.

In order that an airtight relation may be maintained between theflexible sheet and the frame li, a pair of felt strips 21 and 28 aredisposed and retained within the channels, arranged in opposed relationupon the flexible sheet i9. In order that the pressure upon the sheetmay be regulated, the felt strip 28 includes a mounting 29 having ascrew stud 30 threadedly engaged in the frame II. It will be apparentthat by turning the stud 30, to advance the strip 28 toward the glassthe pressure will be increased. The reverse movement of the stud willlessen the pressure. The adjusting means will be provided at both sidesof the frame and at suitably spaced vertical points.

At the lower edge of the flexible sheet in the medial axis thereof, alatch 3| is provided, cooperable with a catch 32 on the lower rail ofthe frame for maintaining the sheet in its lowered operative position.

When it is desired to lower the flexible glass sheet to its operativeposition, it being assumed that the lower end of the sheet is housedwithin the canopy, his only necessary to grasp the latch 3| and drawdownwardly upon the sheet until it reaches its final position, when thelatch may be engaged with the catch 32. When the sheet I9 is beingunwound from the roller IS, the roller I'l functions to re-wind theprotecting sheet l8, but at no time does the sheet l3 become entirelydisengaged from between the convolutions of the flexible sheet on theroller l 6.

An even movement of the transparent sheet I3 is insured by reason of itssecurement to the chains and sprockets 22 and 24. It will be understoodthat the sprockets 22 move in unison since these are secured upon theshaft 2| while the sprockets 24 are freely rotatable upon theirrespective studs 23.

When it is desired to raise the flexible window, the latch 3| isreleased and a slight downward pull on the window will effect rewindingof the window upon the roller I 5, the operation being similar to thatemployed in raising a conventional window shade.

A mechanical means for' raising and lowering the flexible sheet I9 isprovided, cooperable with one of the chains 25 as clearly shown indetail in Figures 4 and 5. An operating means is indicated generally bythe reference character 33, and consists of a frame 34 upon which thereare mounted a pair of dogs and 35, each of which is provided with aspring 31 tending to force thedogs into an engaged position with linksof the chain 25. The upright 38 of the frame II is slotted vertically asat 39, and extended transversely through the slot there is a shafthaving a cam 4| upon the inner end thereof disposed within the frame 34.The cam 4| is provided with a high cam face 42 and a low cam face 43,the former adapted to engage rearward extensions 44 of the dogs when thecam is rotated by means of the hand knob 45. As shown in Figure 4, thedog 35 is held in inoperative position against the tension of the spring31, due to engagement between the high cam face 42 and the rearextension 44 of the dog. Thus the dog 33 is free to engage the chain 25,and in this position downward pressure on the knob will cause acorresponding movement of the frame 34 and associated dogs 35 and 36effecting movement of the chain 25 in a direction to raise the flexibleglass sheet l8. A rotary movement of the knob 45 and associated shaft 40will effect rotation of the cam, releasing the dog 35 so that it will bein operative engagement with chain 25. At the same time, the high camface 42 will have engaged the extension 44 of the dog 38, effectingrelease thereof. Thus, upward sliding movement of the operating means 33will cause a lowering of the flexible sheet glass. The cam face 42should be of an area whereby at one position of its rotation, bothextensions 44 will be engaged, thus freeing both dogs from engagementwith the chain. This position of the dogs will be required when theglass is to be moved by manual downward pull at the latch 31.

In Figure 6, the flexible glass sheet is shown as coiled within itselfby means of a spiral groove 43 formed in respective end walls I4 of thecanopy. In this form the operating mechanism for actuating the window aswell as the protective sheeting may be eliminated, the flexible sheetbeing protected by reason of the spaced convolutions of the groove 46.

The form shown in Figure '7 contemplates coiling the flexible sheetwithin itself solely, a protective sheeting 41 being interwound so as toprotect the facing of the sheet.

In Figure 8, a take-up roll 43 is employed upon which the flexiblewindow is wound, a protective sheet 43 being fed between theconvolutions of the glass sheet, similar to that described in connectionwith Figures 1 and 2. The roll 43 includes a pull cord 50 for rotatingthe roll for raising the flexible window. When the window is lowered,the pull cord will wind upon the roll in position for raising thewindow.

While we have shown and described preferred form of the invention, thisis by way of illustration only, and we consider as our own all suchmodifications as fairly fall within the scope of the appended claims.

We claim:
